St. Catherine's Monastery or the Dominican Monastery is a former monastery and one of the oldest buildings in Tallinn, the capital of Estonia. It is located in the heart of Tallinn's Old Town district full of warehouses and merchants' houses. Its remains constitute one of two remaining medieval monastery complexes in Tallinn.
A Dominican monastery is known to have existed at the site since at least 1246. The site, between present-day Vene and Müürivahe streets, was chosen carefully so as to facilitate both the friar's ability to preach to a large audience, and to suit their business interests, as they are known to have traded in fish. The monastery also had a brewery, producing four types of beer. Throughout the Middle Ages, the monastery was renowned for its scholarship.
In 1524, during the Reformation, the monastery was destroyed. Only fragments remain of the original complex. Parts have been incorporated into the Roman Catholic St. Peter and St. Paul's Cathedral, and other parts, including a finely carved portal, are visible via St. Catherine's Passage (Katariina käik), connecting Vene and Müürivahe streets.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
